Description

Technical Field

[0001] The invention relates to the technical field of parts laser cutting, and in particular to a plate parts laser cutting device. Background Art

[0002] Laser cutting is the use of a high-power density laser beam to irradiate a workpiece to cut and form holes or embossing, trimming and other shapes required by the process. In this regard, in the prior art, common metal laser cutting equipment such as the sheet metal laser cutting platform and laser cutting process disclosed in Chinese patent document CN119077163A includes a cutting table, and a numerical control device for driving the laser cutting head is also provided on the cutting table. As the relative position of the laser beam and the workpiece moves, a continuous slit is eventually formed to achieve cutting of the workpiece. However, when cutting the workpiece, the workpiece must first be transferred to the cutting table and fixed. In actual production operations, especially for sheet metal parts that are continuously transmitted in batches, feed is usually transmitted by a transmission roller group, and how to position and fix the sheet metal parts becomes a problem. Based on existing conventional technical means, multi-directional mechanical arms are often used to clamp and fix sheet metal parts, but the clamping equipment and its accuracy and stability are required to be high, and the operation is more troublesome. Therefore, further research and development and improvement are necessary. Summary of the invention

[0003] In view of this, the purpose of the present invention is to propose a laser cutting device for sheet metal parts to solve the problem that when continuously cutting sheet metal parts in batches by laser, the requirements for the clamping device and its accuracy and stability are high, and the operation is more complicated.

[0004] Based on the above purpose, the present invention provides a plate parts laser cutting device, including a cutting table, and also including:

[0005] A feeding roller set is rotatably connected to the cutting table and is used to convey the plate along the length direction of the cutting table;

[0006] A support frame is fixed on the cutting table, a cutting frame is slidably connected to the support frame, a lifting drive assembly for driving the cutting frame to slide up and down is provided on the support frame, a laser cutting head is slidably connected to the cutting frame, a pressing frame is connected to the side of the cutting frame away from the laser cutting head, and a vertical plate is connected to the bottom end of the pressing frame;

[0007] The roller is rotatably connected to the cutting table. The axial direction of the roller is parallel to the axial direction of the feeding roller group. A notch is provided on the top of the roller to make the cross-section of the roller fan-shaped. The rollers are symmetrically arranged on both sides below the support frame. When the plate is transmitted to the support frame, the cutting frame is driven down by the lifting drive assembly, the vertical plate moves down and pushes the rollers at the rear side, driving the rollers to rotate synchronously, and the plate is lifted upward by the rollers.

[0008] Preferably, the feeding roller group includes a conveying roller arranged parallel to the width direction of the cutting table, a plurality of conveying rollers are arranged at intervals, and the rotating roller is located between adjacent conveying rollers.

[0009] Preferably, the side ends of the rotating rollers are connected to roller shafts, and are rotatably connected to the cutting table through the roller shafts. The roller shafts are connected to pulleys, and a conveyor belt is tensioned between the pulleys to drive the rotating rollers on both sides to rotate synchronously.

[0010] Preferably, a vertical slide rail is provided on the support frame, the cutting frame is slidably connected to the vertical slide rail, the lifting drive assembly is a lifting cylinder provided on the support frame, and the output end of the lifting cylinder is connected to the cutting frame.

[0011] Preferably, a transverse slide rail is provided on the cutting frame, a slider is slidably connected to the transverse slide rail, and the laser cutting head is connected to the slider.

[0012] Preferably, a transverse driving motor is provided on the cutting frame, and a lead screw is connected to the output end of the transverse driving motor. The lead screw passes through the slider and is meshed with the slider.

[0013] Preferably, a waste collection box is provided below the cutting table.

[0014] Preferably, a baffle is provided on the rear roller, and the length direction of the baffle is parallel to the axial direction of the roller. When the roller pushes the plate upward to lift the plate, the baffle pushes the front end of the plate so that the rear end of the plate abuts against the upper limit of the vertical plate.

[0015] The beneficial effects of the present invention are as follows: a feeding roller group connected to the cutting table by rotation is used to rotate and transport the plate along the length direction of the cutting table; a support frame is fixed on the cutting table, a cutting frame is slidably connected to the support frame, a laser cutting head is slidably connected to the cutting frame, a pressing frame is connected to the side of the cutting frame away from the laser cutting head, a vertical plate is connected to the bottom end of the pressing frame, and rollers are rotatably connected in the cutting table, and the rollers are symmetrically arranged on both sides below the support frame. When the plate is transported to the support frame, the cutting frame is driven down by the lifting drive assembly, the vertical plate moves down and pushes the rollers on the rear side, driving the rollers to rotate synchronously, and the rollers are pushed upward by the rollers to lift the plate. Lifting the plate, at this time, the plate is lifted up and separated from the feeding roller group, so that it will not move forward further, playing a role in stable positioning and cutting. During the cutting process, even if the rear plate is transmitted to the bottom of the support frame, it will abut against the rear limit of the vertical plate and cannot be transmitted forward further. Compared with the traditional use of multi-directional mechanical arms to clamp and fix plate parts, the equipment is simplified and the operation is relatively simple. If a pressure plate is fixedly connected to the bottom end of the pressing frame and the pressure plate is moved downward to press the plate, the pressing force needs to be large, the positioning is unstable, and hard friction is generated between the bottom end of the plate and the rotating feeding roller group, which will also damage the feeding roller group or the plate.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, a plate part laser cutting equipment comprises a cutting table 1, and also comprises a feeding roller group 2 rotatably connected in the cutting table 1, and is used to convey a plate 100 along the length direction of the cutting table 1, a support frame 3 is fixed on the cutting table 1, a cutting frame 4 is slidably connected to the support frame 3, a lifting drive assembly 5 for driving the cutting frame 4 to slide up and down is provided on the support frame 3, a laser cutting head 6 is slidably connected to the cutting frame 4, a pressing frame 7 is connected to the side of the cutting frame 4 away from the laser cutting head 6, a vertical plate 8 is connected to the bottom end of the pressing frame 7, a rotating roller 9 is rotatably connected in the cutting table 1, the axial direction of the rotating roller 9 is parallel to the axial direction of the feeding roller group 2, a notch is provided at the top of the rotating roller 9, so that the cross section of the rotating roller 9 is designed in a fan shape, and the rotating roller 9 is symmetrically arranged on both sides below the supporting frame 3, and when the plate 100 is conveyed to the supporting frame 3, the cutting frame 4 is driven to descend by the lifting drive assembly 5, the vertical plate 8 moves down and pushes the rotating roller 9 at the rear side, drives the rotating roller 9 to rotate synchronously, and lifts the plate 100 upward by pushing the rotating roller 9.

[0025] The present invention is based on the existing metal laser cutting equipment, including a cutting table 1, and also includes a feeding roller group 2 rotatably connected to the cutting table 1, wherein the feeding roller group 2 includes a conveying roller 200 arranged parallel to the width direction of the cutting table 1, and a plurality of conveying rollers 200 are arranged at intervals, and the plurality of conveying rollers 200 rotate in the same direction and are used to rotate and convey the plate 100 along the length direction of the cutting table 1, and a rotating roller 9 is located between adjacent conveying rollers 200, and a supporting frame 3 is fixed on the cutting table 1, and a cutting frame 4 is slidably connected to the supporting frame 3, and a lifting driving assembly 5 for driving the cutting frame 4 to slide up and down is provided on the supporting frame 3, and a laser cutting head 6 is slidably connected to the cutting frame 4, and a pressing frame 7 is connected to the side of the cutting frame 4 away from the laser cutting head 6, and a vertical plate 8 is connected to the bottom end of the pressing frame 7, and at the same time, a rotating roller 9 is rotatably connected in the cutting table 1, and the axial direction of the rotating roller 9 is parallel to the axial direction of the feeding roller group 2, and a notch is provided at the top of the rotating roller 9, such as Figure 1 , Figure 2 As shown, the cross section of the roller 9 is designed to be fan-shaped. The rollers 9 are symmetrically arranged on both sides below the support frame 3. When the plate 100 is transferred to the support frame 3, the cutting frame 4 is driven to descend by the lifting drive assembly 5, as shown in FIG. Figure 2As shown, the cutting frame 4 drives the laser cutting head 6 to move down and start cutting, while driving the vertical plate 8 to move down synchronously and push the notch of the rotating roller 9 on the rear side, thereby driving the rotating rollers 9 on both sides to rotate synchronously, and then push upward and lift the plate 100 through the rotation of the rotating rollers 9. At this time, the plate 100 is lifted up and separated from the feeding roller group 2, so that it will not continue to move forward, playing a stable positioning and cutting role. During the cutting process, even if the rear plate 100 is transmitted to the bottom of the support frame 3, it will abut against the rear limit of the vertical plate 8 and cannot continue to be transmitted forward. Compared with the traditional use of multi-directional mechanical arms to clamp and fix the plate 100 parts, the equipment is simplified and the operation is relatively simple. If a pressure plate is fixedly connected to the bottom end of the pressure frame 7 and the pressure plate is moved downward to press the plate 100, the pressing force needs to be large, the positioning is unstable, and the bottom end of the plate 100 will generate hard friction with the rotating feeding roller group 2, which will also damage the feeding roller group 2 or the plate 100.

[0026] Components such as distance sensors for sensing the position of the plate 100 may be provided on the rollers 9 inside or at the rear of the cutting table 1 or at the bottom of the vertical plate 8, and the cutting action is triggered by sensing that the plate 100 is transported to a specific position.

[0027] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the side end of the rotating roller 9 is connected with a roller shaft 91, and is rotatably connected to the cutting table 1 through the roller shaft 91, and an elastic component such as a torsion spring may be provided at the rotating connection. After the cutting is completed, the lifting drive assembly 5 drives the cutting frame 4 to rise, and the cutting frame 4 drives the laser cutting head 6 and the vertical plate 8 to rise synchronously, so that the roller shaft 91 rotates and resets. At this time, the cut plate 100 falls into the cutting table 1, and is continuously conveyed and discharged by the feeding roller group 2, and the falling process is conducive to shaking off the waste or residue cut on the plate 100. Specifically, a pulley may be connected to the roller shaft 91, and a conveyor belt is tensioned and connected between the pulleys to drive the rotating rollers 9 on both sides to rotate synchronously.

[0028] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, a vertical slide rail 31 is provided on the support frame 3, and the cutting frame 4 is slidably connected to the vertical slide rail 31. The lifting drive assembly 5 is a lifting cylinder provided on the support frame 3, and the output end of the lifting cylinder is connected to the cutting frame 4.

[0029] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, a transverse slide rail 41 is provided on the cutting frame 4 , a slider 42 is slidably connected to the transverse slide rail 41 , and the laser cutting head 6 is connected to the slider 42 .

[0030] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the cutting frame 4 is provided with a transverse driving motor 43, and the output end of the transverse driving motor 43 is connected to a screw rod 44, which passes through the slider 42 and is meshed with the slider 42, thereby driving the slider 42 and the laser cutting head 6 to slide laterally.

[0031] Alternatively, the support frame 3 may also be provided with an existing CNC mobile device for driving the laser cutting head 6 to move along a complex path, thereby achieving cutting of complex graphics.

[0032] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, a waste collection box 10 is provided below the cutting table 1 .

[0033] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, a baffle 11 is provided on the rear roller 9, and the length direction of the baffle 11 is parallel to the axial direction of the roller 9. When the roller 9 pushes the plate 100 upward to lift it, the baffle 11 pushes the front end of the plate 100 so that the rear end of the plate 100 abuts against the upper limit of the vertical plate 8.
